President Trump again slammed the Democrats on Sunday.

President Trump has complained that his campaign was "seriously spied upon by intel agencies and the Democrats."
"Think of it," he tweeted Saturday. "I became President of the United States in one of the most hard fought and consequential elections in the history of our great nation. From long before I ever took office, I was under a sick & unlawful investigation concerning what has become known as the Russian Hoax." 
"My campaign was being seriously spied upon by intel agencies and the Democrats," Trump continued. "This never happened before in American history, and it all turned out to be a total scam, a Witch Hunt, that yielded No Collusion, No Obstruction. This must never be allowed to happen again!" 
The president has argued before that he has been spied on. 
Last month, Attorney General William Barr told a Senate panel about Trump's 2016 campaign, "I think spying did occur." 
And though he fought back against criticism over his use of the word, FBI Director Christopher Wray later stated, "That's not the term I would use," but said the FBI was still helping to look into the matter.
